74856-75-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74856-75-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,5 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74856-75:
(7*7)+(6*4)+(5*8)+(4*5)+(3*6)+(2*7)+(1*5)=170
170 % 10 = 0
So 74856-75-0 is a valid CAS Registry Number.

SYNTHESIS OF ANTHRACYCLINONES VIA o-QUINODIMETHANES
Farina, Francisco,Primo, Jaime,Torres, Tomas
, p. 77 - 80 (2007/10/02)
The preparation of several key intermediates in the sysnthesis of anthracyclinones is described.The key step in the construction of the C ring of the tetracyclic system involves a Diels-Alder reaction with an appropriate o-quinodimethane.
